Abstract
Mutations in Aero1 promote the silver flecking (aeromaculata) commonly seen on wild-type pea (Pisum sativum L.) leaves, resulting in a phenotype known as supaeromaculata. We show here the MIII/122 line carries a supaeromaculata mutation allelic to the type aero allele (aero1-1). MIII/122 (aero1-10) and aero1-1 were also found to attain an adult leaf form, flower and undergo apical arrest earlier than their wild-type progenitor, cv. Virtus and cv. Torsdag, respectively. Principal component analyses indicated that in both cases these characteristics co-segregated with the supaeromaculata phenotype. These results suggest that Aero1 is associated with the timing of plant development. Plants carrying an aero1 mutation become fully adult and reproductively competent sooner than their wild-type counterparts, suggesting Aero1 is required to delay these aspects of plant development. Thus, Aero1 represents a previously unrecognized heterochronic gene in the garden pea. Copyright © Physiologia Plantarum 2003.
